A body moves on a frictionless plane starting from rest. If S_n is distance moved between t=n-1 and t = n and S _ n -1 is distance moved between t = n -2 and t = n -1 , then the ratio S _ n -1 ~S _ n is (1- 2 x ) for n =10 . The value of x

Question

A body moves on a frictionless plane starting from rest. If S_n is distance moved between t=n-1 and t = n and S _ n -1 is distance moved between t = n -2 and t = n -1 , then the ratio S _ n -1 ~S _ n is (1- 2 x ) for n =10 . The value of x is ______.
